p class="Normal1"> Este trabalho tem o objetivo de analisar a influência da incorporação da cinza do bagaço da cana na resistência à compressão de misturas secas de concreto, visando sua utilização em pavimentos intertravados. A caracterização física e química da cinza foi feita por meio de ensaios de massa específica e finura Blaine, fluorescência e difração de raios-X, granulometria a laser e microscopia eletrônica de varredura. Foram moldadas misturas secas de concreto, partindo de um traço de referência utilizado por uma fábrica de artefatos de concreto. As substituições variaram de 5 a 50% em massa, tanto no cimento como na areia. Os ensaios de resistência à compressão mostraram um aumento na resistência aos 7 dias, em substituições de até 20% no cimento. Aos 28 dias, entretanto, todas as misturas com cinza apresentaram resistência à compressão inferior ao traço de referência. Concluiu-se que o efeito físico causado pela alta finura da cinza pode ter melhorado o empacotamento no início, mas sua baixa pozolanicidade resultou num menor crescimento da resistência à compressão aos 28 dias. </p
... Use of bagasse in porcelain stoneware increased linear shrinkage and water absorption ability along with reduced flexural strength (Schettino and Holanda, 2015). v.

Increase in industrialization and urbanization has resulted in pollution of available land, and most of the agricultural land has turned into construction sites lately. Large proportion of the agricultural land is black cotton soil having high swelling and shrinkage property. Thus the soil should be treated or replaced with a suitable and effective material to enhance its mechanical properties for construction of buildings, referred as soil stabilization. Cost-effective and economically feasible solutions for waste management are the valorisation of waste from sugarcane industries using dry bagasse and fly ash from coal power plants in improving soil characteristics. This review provides comprehensive understanding on use of fly ash in combination with dry bagasse as an effective soil stabilizer.

The issue of increasing demand for building materials has provided a need for
sustainable materials to be manufactured with proper waste usage. In this paper, an
experimental investigation was carried out on a paver block to study characteristics
of Ground granulated blast furnace (G.G.B.S.), Iron fillings & glass fibers. Ground
granulated blast furnace (GGBS), Iron fillings, fly ash & glass fibers were used and
the effect of their addition on paver block, behavior was studied. Results has given
the addition of G.G.B.S., iron & glass fibers increased the compressive strength,
flexural strength & water absorption as compared to conventional paper block. For
the development of the paver block, G.G.B.S., Iron fillings, Glassfibre is used as a
partial replacement of cement & fine aggregate (FA) & coarse aggregate (CA)
respectively. The develop product was tested according to the Indian Standards (IS)
& the effect of addition of GGBS, iron & glass fiber was tested. The combination of
Iron fillings (4%) + Cement (21%) + F.A. (25%) + C.A. (50%) has given the
compressive strength of 62.10 MPa & flexural strength 6.2 MPa. Water absorption
is 4% which is also within the limit. Hence, the study concluded that the use of
above waste materials, as an alternative raw materials for the production of paver
block was feasible.
... Parthini and Gifta [10] proposed to produce interlocking concrete pavement blocks using sand without curing in order to reduce the landfill problem. Rajkumar et al.

The interlocking concrete pavement blocks are quite commonly used to construct the pedestrian walkways and parking lots of transport infrastructure. Such blocks need adequate compressive strength to withstand the design live loads. In this paper, the influence of admixtures on the compressive strength of the blocks are studied through a series of laboratory investigations. The M35 grade of concrete conforming to the Indian Standard code of practice has been used with a standard superplasticizer as admixtures added at specified weights. The study implied that the use of admixtures alters the compressive strength of concrete blocks significantly.
... It is found that at 15% replacement of bagasse ash with concrete at 28 days shows a good compressive strength [5]. The design life and maintenance of SCBA paver block is high in comparison with the design life of conventional flexible pavement [6,10]. Unlike traditional concrete, the mix design of permeable concrete is different [29]. ...
Pervious concrete has newly undertaken to escalate for its demand. As urban areas develop, the difficulties related to runoff management have become more herculean and pervious concrete can provide a sustainable solution. Sustainable development in the field of concrete structures can be achieved by minimizing the usage of cement in concrete as it releases a large amount of CO 2 leading to various hazards. The reduction of Portland cement is attained by replacing by-product from various industries. Sugarcane bagasse ash (SCBA) is obtained by burning sugarcane after the extraction of all efficient sugar from it. Disposal of the ash material causes various environmental hazards. Strength is improved by using SCBA as a supplementary material and thus makes the resultant concrete eco-friendlier and economical. The bagasse ash which passes 150 lm and retained on 90 lm similar to that of OPC is used in this study. The samples are prepared by replacement of bagasse ash with cement in different percentages and the strength parameters and permeability of concrete is tested. Six different concrete mixes with the bagasse ash replacing 0%, 5%, 10%, 15%, 20% and 25% of the OPC were prepared with water to cement ratio of 0.34 and 202.83 kg/m 3 cement content. It is found that at 15% replacement, the optimum strength is obtained. Since the aggregate sizes used for all the percentage replacements remains same, the permeability ranges from 0.2 cm/s to 0.4 cm/s.

The plastic waste is available in large quantity so the cost of paver block gets low. ...
... It was concluded that the preparation of tiles consisting of 50% clay, 15% quartz, and 35% feldspar was obtained from a local manufacturer and feldspar as partially replaced in sugarcane bagasse ash. The sugarcane bagasse ash materials are used mostly as other structural elements compounds like fly ash bricks as a replacement-level up to 20% of SCBA along with lime content thus resulting the various strength attainment in the fly ash bricks with different curing days and also noted that the less water absorption due to improvement of pozzolanic reaction over period of hydration to produce the gel formation [5][6]. The chemical reaction between the binding materials along with water to form an addition gel formation while addition of SCBA content in Portland cement due to more amount of silica oxides presents in the SCBA which gives the fewer chloride ions permeability in concrete when compared to fly ash and slag or cementitious materials in conventional concrete for different curing days and all the values are satisfied as prescribed in various codes [7][8]. ...
This research work has been investigated the agriculture solid waste of sugarcane bagasse ash (SCBA) materials replacing Portland cement and produces the assured quality of concrete. The current research work for various mixes of experimental test results shows the higher compressive strength was 37.51MPa at 28-days, 38.10 MPa at 56-days, the best mix consisting of SCBA (wet sieving method) content up to 15% (by weight of binding materials) along with 1.5% of waste tin fibers and also an excellent improvement trend was noted in flexural rigidity of concrete to addition of tin fibers shows the higher bending stress for all mixes except reference as well as more than 15% of SCBA concrete at different curing days. However, this study focused on the indirect measurement of tensile strength in SCBA concrete obtained the higher split tensile strength was 3.75MPa at 28-days, 3.95MPa at 56-days. It is concluded based on the various test results for different curing days the optimum replacement level of SCBA up to 15% of Portland cement was fixed and achieve the target strength of M25 grade of Portland cement concrete at 28 days.
